第 4 集: 戀愛研究所復活了！至少我們是這麼想的……

Eno becomes the student council vice president and Sayo becomes the treasurer once again. The five members of the student council are as eager as ever to resume their love lab. Riko breaks into a cold sweat when the other members begin treating her as their master of love after she blurts out a lie. (Source: Crunchyroll)
